Thomas (Dylan O’Brien) awakes in a rusted elevator only remembering his first name. The elevator lifts him to “The Glade,” a independent sanctuary populated by a gathering of teenage boys who don’t know how they arrived there. “The Glade” is confined on all sides by a dangerous maze where the walls switch every night and the monstrous Grievers reside. When a girl (Kaya Scodelario) arrives, the Gladers world begins to change. The “Runners,” must solve the maze and crack the code before time runs out.
